How to Calculate GST

GST (Goods and Services Tax) is calculated on the taxable value of goods or services. There are two common scenarios:

GST Exclusive Calculation (Adding GST)

When you have the base price and need to add GST on top:

GST Amount = Base Price × (GST Rate / 100)
Total Price = Base Price + GST Amount

Example: Base price = ₹10,000, GST rate = 18%
GST = 10,000 × 0.18 = ₹1,800 → Total = ₹11,800

GST Inclusive Calculation (Extracting GST)

When you have the total price and need to find the base price and GST component:

Base Price = Total Price / (1 + GST Rate / 100)
GST Amount = Total Price - Base Price

Example: Total price = ₹11,800, GST rate = 18%
Base = 11,800 / 1.18 = ₹10,000 → GST = ₹1,800
